THE BIODIVERSITY STUDY OF SOME ROSA CANINA L. GNEOTYPES FROM OLTENIA AREA
AbstractIn this paper there was studied the variability of some morphological characters from Rosa canina genotypes of 20 local populations from different areas from central and northern part of Oltenia, Valcea County, and also plant association where there were found those ones. The results werestatistically interpreted byanalysis of variance, PearsonCorrelationsandPCA(PrincipalComponent Analysis). There were indentified 3 populations groups: first group with 6 genotypes with high values for both shoot length and flower diameter; second group with 9 genotypes and has low values for both shoot length and for the flower diameter (both negative components) and third group with 5 genotypes and has low values for shoot length and high values for flower diameter. The great variability indentified inside of studied populations is probably caused by the altitude and the phytosociological associations.
